(gcide) | Umbelliferone \Um`bel*lif"er*one\, n. (Chem.)
A tasteless white crystalline substance, C9H6O3, found in
the bark of a certain plant (Daphne Mezereum), and also
obtained by the distillation of certain gums from the
Umbelliferae, as galbanum, asafetida, etc. It is analogous
to coumarin. Called also hydroxy-coumarin. Its strong
fluorescence under ultraviolet light makes it useful in
analytical biochemistry, as, for example, to detect
phosphatase activity by hydrolysis of umbelliferyl phosphate.
